Now it looks perturbed. It scuttles around, producing more drones, but quickly it does, in fact, run out. The last few don't head out and seem to hover near the thing itself, scanning in all directions defensively. The big guy clambers to the top of the crater and... is... doing... something.
Its legs stiffen and its claws dig into the ground. Angry magenta light runs down the sides of the arches that make up its spine, its eyes glow brighter, and the luminous rings on his shoulders and neck slowly grind and begin to turn. The air feels like it's vibrating.
The lava in the crater—gushes. There comes a fountain eruption, then another, higher, the slag splashing and dripping off the giant mechanoid salamander. The rock base of the crater breaks and sinks as liquid level rises; lava slops over the edge of the caldera, joining the running rivers on the slopes, which are themselves surging with accelerated flows.
